The BAR seems to be enabled. Btw I tried to boot Win7 but still got only logo animation forever. Not sure what it could be.
I agree that this patch is big improvement. We can fix the MMCONF later.
Was that an ack?
Maybe I misunderstand, but I don't think that there is an MMCONF issue. The bar disable prevents the 780 MMCONF from being moved, right?
Just curious, have you test this with Linux? I tried to load win7, but got a ACPI stop 0xA5. I suspect that my tables are not working at all. This is on iei kino. I will investigate more tomorrow.
